*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point
The new SRF (Super Response Fluid) and LVS (Low Vibration Spring) have been adopted to achieve unprecedented levels of both driving and ride comfort.
The newly adopted retainer, which receives the spring load and eliminates the bending load on the spring and absorbs torsion to improve the movement of damper, enabling the LVS (Low Vibration Spring) to demonstrate its performance in any situation.
New parts are adopted internally to enable a wide range of settings with a large amount of dial range, resulting in higher durability.
Special color insulators with a sporty vibe have been adopted to the front and rear spring seat to create a striking appearance and smoother slide during ride height adjustment, making adjustment easier.
The test vehicle is equipped with a rear roll cage, which is often required for tracking. A strut tower bar and mechanical LSD are also installed to be similar with the racing specifications.
The test vehicle is the early model of S2000, which is considered difficult to control. However, the setting makes it surprisingly controllable and allows the driver to feel the rear grip traction as far as possible.
In order to meet the needs of driving with the lastest high-grip radials, ADVAN A052 are installed and tested on Fuji Speedway.
The recommended damper force level on Fuji Speedway are 7 click front and 8 click rear. The vehicle height balance is optimized at the time of shipment based on the results of driving tests.
If you focus on driving on track than street driving, please increase 2 kgf/mm spring rate, which allows to accelerate actively. Please enjoy the sharply cornering!
